JOHN H. GOEBEL, OF CHICAGO, ILLINOIS.

POURING NOZZLE FOR BOTTLES.

Application filed April 3,

To all whom t may concern:

Be it known that I, JOHN H. GoEBnL, a citizen of the United States of America, residin at Chicago, in the county of Cook and tate of Illinois, have invented a certain new and useful Improvement in Pouring Nozzles for Bottles, of which the following is a specification.

This invention relates to that class of pouring Stoppers or nozzles for milk bottles and the like by means of which an even and uniform pouring action is attained, and the usual gurgling action caused by the inflowing air avoided, and the present improvement has for its object To provide a compact structural formation and combination of parts adapted to afford a substantial connection of the stopper to the mouth of the bottle, and which is capable of ready disconnection and is 4adapted to attain an even and uniform outflow of theV contents of the bottle/al1 as will hereinaftermore fully appear.

In the accompanying drawings:

Fig. l, is a central sectional elevation of a stopper and bottle neck, showing the preferred construction of the present improve-k ment.

Figs. 2 and 3, are similar views of modified forms of the preferred construction.

Like reference numerals indicate like parts in the different views.

Referring to the drawing, 1 designates the central and circular body portion of the stopper formed with an upper marginal flange 2, adapted to limit the entry of the stopper into the neck of a bottle by contact with the top end thereof. The body portion 1 is at its upper end formed with a convex crown having an obliquely arranged lateral extension 3 constituting the outlet spout of the. stopper, as hereinafter more fully set forth, At its lower end tla body portion 1, is formed with a reduced circular extension 4, the periphery of which is of a reversely curvedy form in cross section to provide an upper annular concave channel or recess 5, and a lower annular convex holding rim 6, as shown.

7 designates an attaching gasket of cork or like elastic and fluid repellent material, 0f an annular form and having the surface 1922. serial No. 549,323.

of its circular orifice of a reversely curved form corresponding with that of the stopper extension 4 and adapted to lit and have substantial attachment thereto.

The described construction while affording a substantial connection between the gasket 7 and neck or extension 4 of the stopper, and which is necessary in view of the lesser peripheral contact of the parts over what is provided by the perimeter of the gasket, is adapted in addition to afford an increased volume of elastic material at the mid-height of the gasket to afford an yeffective expansive holding contact between the gasket and the inner surface vof the bottle neck.

The overhanging top flange 2 of the body portion l may have direct contact with the top of the bottle neck as shown in F ig. 2, but it is preferableto form the gasket 7 with an outstanding top flange 8 adapted to constitute an intermediate bearing between the stopper flange 2 and the top of the bottle neck, as shown in Figs. l and 8.

9 designates a main curved orifice extending from the inner face of the extension 4 through the body portion 1 and through the spout 3, to constitute the pouring orifice of the nozzle.

l() designates a vent passage formed in spaced relation to the pouring orifice 9 aforesaid, to admit a readv entrance of air to the interior of the bottle and avoid the usual gurgling action of such air. The passage 10 may open into the passage 9 as shown in Figs. 1 and 2, or be separate therefrom as shown in Fig. 3.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent, is

1. A pofuring stopper for bottles comprising a main body having a convex crown formed with an oblique spout or extension,

a marginal stop flange and depending extension the periphery of which is of a reversely and annular curved form, and an annular gasket the opening of which has a reversely curved shape to fit said lower extension, the stopper having the usual pouring and vent passages.
